Abstract (en)
An optical surge suppressing apparatus includes an output light level compensating circuit, an optical surge compressing circuit, and an optical amplifier. The output light level compensating circuit compensates for a level drop generated in input signal light. The optical surge compressing circuit suppresses an optical surge generated in the input signal light. The optical amplifier outputs the input signal light in which the level drop is compensated for by the output light level compensating circuit and the optical surge is suppressed by the optical surge compressing circuit. <IMAGE>
